Blade Type
Blade Type

The Bunka is your small/medium sized prep solution. If you prefer a slightly shorter blade length but still need to prep veggies and smaller cuts of meat, this is your stop. The angled "K-Tip" allows for finer tip work and can be used to sweep ingredients across the board so you don't dull your edge.

Steel Type
Steel Type Read

Japanese Blue Super Steel, an elite variant of the "Aogami" series, is a high-carbon steel alloyed with chromium, tungsten, and added vanadium. This composition enhances its wear resistance, edge retention, and overall toughness. It will still rust if left wet for too long, but not as quickly as any of the other carbon steels. Favored in fine knife crafting, Blue Super Steel is renowned for producing exceptionally sharp and durable Japanese knives.

Yu Kurosaki has become one of Japan’s most celebrated blacksmiths, known for his bold aesthetic choices, cutting-edge techniques, and dedication to pushing the boundaries of traditional knifemaking. Beginning his journey in his teens and apprenticing for 12 years under Hiroshi Kato, Kurosaki established his own forge in 2014 and has since earned recognition from the Japanese government as the youngest ever to be named a Master Blacksmith.

His knives are instantly recognizable for their striking Tsuchime and Suminagashi finishes, thin grinds, and use of high-performance steels such as SG2, HAP40, and stainless-clad Blue Super. Kurosaki’s Fujin series, with its dramatic wind-patterned hammer finish, helped cement his reputation as a blacksmith who blends artistry and technical brilliance in equal measure.

Lovely buying experience. Fantastic hardware, with warm and extremely knowledgeable guidance from the staff. I particularly enjoyed the emphasis on steel quality, and the philosophy of the artisan blacksmiths inherent in the knife’s creation. Highly recommended. Also, most of the knives are not much more expensive than a decent department store where they won’t know the background knowledge
